I am so glad your son is OK. My son rides one too and I worry all the time. There is no protection on them and other drivers don't watch for them or respect them on the road. My son tells me I paranoid but after my nephew was killed 2 years ago in a car accident, I have realized how precious life really is. I am so happy your son is OK. Sleep well. The center will wait. Your priority is taking car of your son.
